My understanding is that the problem isnt a bug in the traditional sense. Obviously take this with a grain of salt as im not an employee. But i feel like i remember a player(or maybe a couple?) doing a few test runs on the easy/very easy "bug". And based on their observations, a lot of BJJs more dangerous moves were timed based on hp%. What that meant in practice was that on the easiest setting, he was hitting big moves more quickly and the player was having less time to combo/LB cycle to regain hp. Combine that with someone who struggles to any serious degree with dodging, and you get a lethal mixture. That, and im also under the impression that if you fail the towers mechanic the fight cant progress. And for someone struggling, having a make or break move happen 5ish minutes into the fight doesnt help.

So not being traditionally broken means that it wouldnt show on their end aside from in specific testing circumstances, and also means that a fix might require a touch of art. Youd probly do some combination of reducing incoming damage, increasing healing per combo, increasing healing per LB(maybe have it last 5 more seconds?), potentially an extra life(scaling based on failures perhaps?) for Wuk, and possibly loosening the towers mechanic(altered timing? he keeps doing it until you die or get it right? not positive here but some idea would probly work).

Or i could be full of it, and none of this that i remember was accurate. In which case, disregard me.
